Thanks for all of the sticky vibes- it may be working. I've been trying not to think much about this until I see the RE again on Thursday. Last night was terrible, bad cramps and quite a lot of spotting, but my temp was still up this morning and nothing more today.
I'm pretty emotionless right now- my only saving grace. I'll keep you all posted. Thanks so much for the support. I've not told anyone IRL except my DH, and I can't really talk with him about it. He's supportive, but practical, and just doesn't get it.
If this is a chemical, at least we know I can conceive, right? That's information we didn't have previously. We can address that for future pregnancies, if it comes to that. I'm just trying to find the silver lining here.
Keep yourself super chill. We're rooting for you.
